Apparently if you book a roundtrip and want to change only a one way trip they must book the entire flight all over again causing an enormous jump on price and fees. What they also don't tell you is that you could go directly to the airline and change it through them without any fees. The first time I booked anything thru Priceline was a hotel and when I showed up to hotel they were BOOKED. Priceline took an hour to be able to find me another hotel that was not one I intended to stay in the 1st place. The customer service reps are rude and will get in a screaming match with you knowing they did not offer proper service. read full review »
